En zelfs: "Use of another acid, such as sulphuric acid to neutralise pool alkalinity will reduce the pH but will produce sulphate ions rather than chloride ions. Sulphate ions conduct electricity equally well as chloride at the electrode, but will not produce any chlorine. A salt water pool "poisoned" with sulphate may have to be drained and refilled to remove the offending sulphate ions."
But, what is on the label of our small (now depleted) tank, apart from it being a product especially for "Cloractión Salina"?
SULFURIC ACID!
Engineer Jansen is quite (sul)furious.
